Abstract
Adjustment of a read detection equalizer filter of a magnetic tape drive is conducted utilizing a required control pattern signal which comprises a required portion of a normal recording format of the magnetic tape. An example comprises a data set separator signal. The sensed required control pattern signal is processed with respect to a target reference pattern signal to adapt the read detection equalizer filter to the target reference pattern signal.
